Halfway Between 4 and 420

When you ask "What number is halfway between 4 and 420?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=4 and Y=420.

Halfway Between Line

To find the number halfway between 4 and 420, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 420 into our formula, we get:

(4 + 420)/2 = 212

Thus, the number halfway between 4 and 420 is 212.

To check that our answer is correct, we subtract 4 from 212 and subtract 212 from 420 and compare the two numbers:

212 - 4 = 208
420 - 212 = 208

As you can see, the halfway number is 208 higher than 4 and 208 lower than 420. Therefore, our halfway between answer of 212 above is correct.
